VAPOR-BURNER.

Application filed December 6, 1915.

T 0 all whom it may concern:

Be it known that I,\/VILFRID G. CHAUSSE, a subject of the King of Great Britain and Ireland, residing at Detroit, in'the county of \Vayn'e and State'of Michigan, have invented, certain new and useful Improvements in Vapor-Burners, of which the following is a specification,

This invention relates to improvements in vapor-burners and particularly to that class of portable vapor-burners using hydro-carbon fuel, which are designed to give intense heat so as to be usedas paint burners, heaters for soldering irons, and for brazing, melting snow and ice from switch points and similar purposes;

In many of the structures of this class, in use at the present time, the means for feed ing fuel from the fuel reservoir to the burner proper is of such a nature that the usefulness of the burner is curtailed because if it is used in certain positions the fuel will not flow properly from the reservoir to the burner, and to workefficiently these burners must be held in certain positions.

j The objects of this invention are: First, to provide a device of this nature, comprising a fuel re ervoir and burner, so connected that the fue will always flow from the reservoir to the burner irrespective of the position in which the deviceis used. Second, to provide in a vapor-burner, an improved feeding device automatically actuated by change in position of the fuel reservoir so as to open the fuel inlet of said feeding device which shall be lowermost at that position of the reservoir. Third,.to provide in a vaporburner a feeding device comprising a feed tube having a pair of fuel inlets and means automatically actuated by a change in position of the reservoir, to open the lower most fuel inlet and close the uppermost fuei inlet. Fourth, to provide in a vapor-burner a fuel feeding device comprising a feed tube having a pair of fuel inlets, and automatic me'ans operated by gravity for opening and closing said inlets, one or the other of said inlets being always open Fifth, to provide in a vapor-burner a feeding device having a pair of fuel inlets and automatic selective means for opening the fuel inlet nearest the lowest pointin the fuel reservoir.

economies of manufacture and details of construction will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and. pointed out in the claims. I

A structure constituting an embodiment of my invention is clearly illustrated in the accompanying drawings forming part of this specification in which:

Figure I is a view in side elevation of a vapor-burner constructed in accordance with my invention, a part of the fuel reservoir being broken away to show the feed tube. Fig. II is a longitudinal, sectional view on the line 2.2-of Figs. III and IV. Fig. III is a transverse, sectional view through the feed tube on the line 3.*3 of Figs. I and II. Fig. IV is a transverse, sectional view through the feed tube on the line 4-4 of Fig. II. Fig. V is a view inside elevation of a modified form of feed tube. Fig. VI is a longitudinal, sectional view. of the modified form of .feed tube. taken on the line 66 of Figs. VII and VIII. Fig. VII is atransverse, sectional'view on the line 77 of Figs. V and VI. Fig. VIII is a transvers sectional view on the line 88 of Figs. ai VI. Fig. IX is a view, in end elei ah i the modified form of feed tube.

In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the sectional lines.

Considering the numbered parts of the drawing,- my improved vapor-burner comprises a fuel reservoir 1 and a burner proper which is designated generally by the numeral 2. The fuel reservoir is provided with an air pump 3 for supplying air pressure to the reservoir so as to force the fuel to the burner proper. A handle 4 is provided and legs 5 are secured to the cylindrical tank or reservoir 1. The burner 2 is-connected I with th fuel reservoir by means of the pipe 6 in w ich there is a cut-off valve 7. The burner comprises a tube 8 provide near its rear end with ope'ningsfi for admitting 10.5

Theseopenings 9 may be closed partly'or wholly by the sliding regulatin shield 10 so as to control the amount of air admitted to the burner. Ears 11, extending downwardly from the tube 8, support the pipe 6 which extends adjacent to the tube 8 so that the fuel is heated by the burner before it reaches its-outlet in the burner. A receptacle 12 is provided in which a quantity of hydro-carhon may be ignited to start the burner as is usual in burners of this type. nipple 13 is threaded into the end wall of the fuel reservoir and the end of the pipe 6 is screwed into the nipple 13. ,A. feed tube 14' extends approximately the length of the reservoir,

as shown in'Fig. I, and one end of this feed tube 14 is threaded into the nipple 13.

In one form of my device, I use a feed tube constructed in accordance with Figs. II, III, and. IV. Aplug 15 is screwed into the farther end of the feed tube and fuel inlet openings 18 and 17 are formed in the wall of said feed tube adjacent the ends thereof. A slide valve, comprising the flanged plungers 18 and 19 carrying the packing rings 20 and 21 and connected by rod is disposed within the feed tube 1.4 with the packing rings 20 and 21 snugly engaging the wall of said feed tube. The length of therod 22 is slightly greater than the distance between the fuel inlet openings 16 and 17, so that, for example, when the packing ring 21 closes opening 1'7 the other-packing ring 20 clears opening 16. A weighttube or "cylinder 23 is disposed within'the feed tube 14 with the rod 22 extending through said cylinder as shown in Fig. II. This weight tube is shorter than rod and is free to slide thereon, the ends of the said weight tube being adapted to engage the plungers 18 and 19. A ring 24: is threaded into the end of the feed tube 14 which is screwed into the nipple 13, said ring serving to limit the move ment of the slide valve.

In Figs. V to IX, I have shown another form of feed tube which may be used in place of. the feed tube shown in Figs. II, III, and IV. In this modification, the feed tube 25 is provided with the fuel inlet openings' 26 and 27 adjacent the ends thereof. Valve seats 28 and 29 are formed on the side of the tube 25 as shown in Figs. V, VI and v VIII. Valves are providedplosing the openings 26 and 27 and comprising the valie stems 30 and 31, having the heads 32 and 33, and packing 3 1 and 35 disposed "around the stems and beneath the heads and normally seating on the valve seats 28 and 29. A

leaf spring 38 is secured at its center to the ings. 26 and 2-7 and are adapted to be engaged by the pointed ends of the bar 38 as shown in Fig. VI. v

From the description of the parts given above, the operation of my device should be very readily understood. The hydro-carbonfuel .in the reservoir 1 is forced under air pressure supplied. by the pump 3, through pipe 6 to the burner 2. The fuel passes into pipe 6 through the feed tube ll. \Vith the parts in the position shown in Figs. I and II, the fuel enters the feed tube 14. through the opening 16, flows the length of the feed tubea'nd passes through the ring 24 into the pipe 6. If the apparatus should be. turned to a vertical position in whichthe reservoir 1 is uppermost and the burner 2 lowermost, the opening 18 would be above the level of the fuel and the fuel would not feed the burner. However, when the apparatus is turned to such a position, the weight 23, in the feed tube 14, falls and engages the flanged plunger 19 moving the slide valve in the feed tube until the movement is limited by the stop ring 24 closing inlet 16 and opening inlet'17, which is beneath the l 'vel of the fuel, so that the flow of fuel to the burner is uninterrupted. Similarly, if the torch should. be turned to a position in which the burner 2 is above and the reservoir 1 is below, the weight 23 would operate, in the feed tube 1 1, to "move the slide valve to a position in which the inlet 17 is closed and the inlet 16, which would in that case be below the fuel level, is opened. It will be seen that the slide valve in the feed tube 14 is automatically actuated, by a change in position of the apparatus, so as to open the inlet which is lowermost and hence below the level of the fuel in the res ervoir. It will also be evident that one or the other of the inlets will always be open. The result is that, by means of the use of my feeding device, the fuel will always be fed to the burner irrespective of the position in which the apparatus is used. The other form of feed tube, which I have shown in Figs. V to IX inclusive, operates on the same principle. The leaf spring 36 tends to keep the valves closed. If the torch should be moved to a position in which the burner is below, the weight 38 moves in the feed tube 25 until it'strikes the cross bar 39 of the stop ring 40. The pointed end of weight 38 engages the valve stem' 31 and lifts the packing 35 away fromthe seat 29 opening the inlet 27. At the same time, the other pointed end of weight 38 moves out of engagement with valve stem 30 and the spring 36' forces the packing 34: against seat 28 closingthe inlet 26. The movement of weight 38 is limited, in one direction by the plug 15, and, in the other direction, by the. cross bar 39 of the stop ring 40. The extrem length of weight 38 is equal to the distance between the valve stems $30 and 31 so that one of the valves will always be open.
